WInd whistle changing to high piercing shrill noise

It has been over 9 years since the car was put back on the road

It has had a whistle I tried finding since getting it on the road

After reading the was a TSB on it and the leading edge trim on the hood might be the problem I taped off the top of the trim before making a 75 mile trip this morning

THE CAR WAS SUCH A PLEASURE TO DRIVE completely whistle free. I could hear wind noise in the right door glass for the 1st time ......... LOL

So once I got to columbus for the cruise in I removed the tape. But before I can home taped it on the bottom side and again drove home whistle free

So anyone with a 67-69 dart with a whistle it would be worth trying to tape the trim off and see if the whistle goes away
